Objective To investigate the chemical constituents from the roots and rhizomes of Rhodiola sachalinensis. Methods The chemical constituents were isolated by repeated silica gel chromatography, medium pressure column chromatography, and semi-preparative liquid chromatography, and their structures were elucidated by chemical properties and spectroscopic analyses. Results Eighteen compounds were isolated and identified to be gallic acid (1), p-hydroxybenzoic acid (2), salidroside (3), benzyl-O-β-D-glucopyranodide (4), phenylethyl-8-O-β-D-glucopyranodide (5), cinnamyl-β-D-glucopyranoside (6), sachalinol (7), quercetin (8), quercetin-3-O-β-D-glucopyranoside (9), kaempferol (10), kaemferol-7-O-α-L-rhamnopyranoside (11), kaempferol- 7-O-β-D-glucopyranoside (12), kaemnpferol-3-O-α-L-rhamnoside (13), kaempferol-3-O-β-D-glucopyranoside-7-O-α-L-rhamnoside (14), tricin (15), tamarixetin (16), herbacetin-7-O-α-L-rhamnoside (17), and herbacetin-3-O-β-D-glucopyranoside-7-O-α-L- rhamnoside (18). Conclusion Compounds 9, 12, and 16 are obtained from the plants in Rhodiola L. for the first time. Compounds 2, 7, 8, 14, and 18 are obtained from this plant for the first time.
